Application November 28, 1949, Serial N o. 129,735 In Sweden February 3,1947 3 Claims. (Cl. 19.2-46) rThe present invention relates tofree-spool fishing reels of the kind comprising a rotatably mountedwinding spool and a rotatably mounted hand crank, the rotary movement ofwhich is transmitted to the spool by means of a releasable couplingcomprising on one hand a rst coupling member rotatable by the crank andprovided with a number of dogs in the path of movement of which, whenthe crank is rotated in order vto wind up the fish line, there aredisposed the ends of I a corresponding number of co-acting elementsmovably mounted on a carrier rotatably and frictionally mounted on ashaft co-axial with the axis of rotation of said rst coupling member,and on the other hand a second coupling member rotatable with the spooland rotatably mounted on a shaft co-axial with the axis of rotation ofthe first coupling member, said second coupling member being providedwith surfaces adapted to co-operate with the aforesaid co-actingelements when these are in an operative position. More particularly theinvention relates to fishing reels of the kind referred to in which themovement of rotation of the first coupling member rotatable by the crankis transmitted to the second coupling member coupled to the spool bymeans of said co-acting elements as the crank is rotated in onedirection, while when the crank is released the spool is free to rotateto the opposite direction without transmitting its movement to thecrank.

The object of the invention is to provide a fishing reel of the kindreferred to which is simple in its construction and reliable in itsaction.

The invention is mainly characterized in that the said co-actingelements adapted to transmit the movement of the first coupling memberto the second coupling member consist of pins slidable substantiallytangentially to an imaginary circle concentric with the couplingmembers.

According to a suitable embodiment the pins are actuated by springswhich normally tend to slide the pins out of engagement with thecooperating surfaces of the second coupling Imember rotatable with thespool.

An embodiment of the invention is shown by way of example on theaccompanying drawing, wherein- Figure 1 is a front elevation of a reelpartly in section and with some portions cut away.

Figure 2 shows certain movement transmitting members shown in thedirection of the arrows II-II in Figure 1.

Figure 3 is a section on a somewhat enlarged scale through the portionof the mechanism shown to the right in Figure 1, and

Figures 4 and 5 show the parts of the coupling in different workingpositions and viewed oppositely to the direction of Figure 2.

In the drawing I and 2 denote two parallel, spaced plates interconnectedby means of screws 3. Between these plates the spool for the fishingline is carried by a shaft 5 journalled in bearings xed to the plates.To the outer side of the plate 2 there is secured a smaller plate 6, andoutside this plate there is provided a toothed wheel I rotationallymounted on a hub 8 and adapted to be rotated through an intermediatecoupling (hereinafter described) by a hand crank 9 mounted on a crankshaft 2l. A small pinion I9 fixed to the spool shaft 5 meshes with thetoothed wheel 'I so that the spool is caused to rotate when the toothedWheel 1 is rotated. Another pinion II secured to a screw I2 journalledin the plates I, 2 also meshes with the toothed Wheel 1, and on saidscrew I2 there is mounted a levelling winding carriage I4 of commonform.

The toothed wheel l, the pinions l0 and II and the aforesaid couplingare situated in a chamber formed by a rim I5 and a cover I6 secured tothe plate 2 by means of screws.

In front of the hub 8 the cover I6 is formed with a cylindricalprojection I'I and in a bushing I8 secured in said projection there isrotationally mounted a sleeve I9 the inner end of which is formed withtwo radially projecting heads 20 positioned diametrically opposite eachother.`

These heads are each formed With a channel 2I disposed mainlytangentially .to an imaginary circle concentric with `the crankshaft 21and the said sleeve I9, and in each channel there is slidable a pin 22actuated by a spring 23 normally tending to keep the pin in the positionshown in Figure 5. The outer end of the sleeve I9 is screwthreaded andhas a nut 24, and by tightening said nut the heads 20 can be caused tofrictionally contact a ring 25 of a suitable material secured betweenthe heads and the inner side of the cover I5. A similar ring 26 isprovided between the nut 24 and the end surface of the projection I1. Inthe sleeve I9 there is journalled the crankshaft 27 to the outer end ofwhich the hand crank 9 is secured, and to the inner end of thecrankshaft there is secured a hub 28 formed with two radially projectingwings 29 disposed diametrically opposite each other. In the path ofmovement of said wings, as the hand crank is rotated in a clockwisedirection with respect to Figure 2 the enlarged ends 30 of the pins 22are disposed. As the crank 9 is rotated the wings 29 abut the ends 30 ofthe pins 22I and slide the pins 22 from the position shown in Figure tothe position shown in Figure 4, Whereupon the wings cause the heads 20and the sleeve I9 to rotate with them. As soon as the crank is releasedthe springs 23 slide the pins 22 back to .the position shown in Figure 5whereby the wings 29 and the crank Shave imparted to them a slightbackward movement. To the side of the toothed wheel 'l facing towardsthe cover I6 there is secured a sleeve 3l, which surrounds the heads 29and the wings 29, and is internally formed with a suitable number(according to the embodiment shown, four) evenly spaced sloping stepsurfaces 32 which, when the pins 22 occupy the position shown in Figure4, are in the path of movement of the ends of the pins opposite-theenlarged ends 3i) and co-operate with same so that the sleeve 3| andthus the toothed wheel 'l are caused to rotate as the crank 9 isrotated.V With the coupling described the spool is imparted apwinding uprotation as the crank 9v is rotated in a clockwise direction withrespect to Figure 2, while, when releasing the crank, the crank; and thespool are automatically disconnected; from each other, so that therotation of the spool is not transmitted to the crank when a cast ismade.

The invention is notl limited to the embodiment describedv above andshown in the drawing but may bel varied in details without departingfrom thespirit. For instance the springs 23 can be dispensedrwith, andin such a case thev coupling disengagesthe connection between the spooland thecrank; at the beginning of the unwinding movement of the spoolvwhen a cast is made, as the sloping-step surfaces 32k of the sleeve 33vpush the pinsY 22,out of engagement with themselves, imparting. to ,the,wings 291and to the released crank 9 aL slight movement intheanti-clockwise direction.

A onefway. clutch for fish reels having adriving shaft anda drivenshaft for rotating the line winding reel thereof comprisinga sleeverotatably mounted on said drivingA shaft, a pair ofdiametricallyopposite headsmounted on said sleevei a plurality of pins',each of said heads having a channel formed, therein in a substantiallytangential direction with reference to an imaginary circley concentricwith-,said driving shaft and each of ,saidpinsbeing slidably mounted inone of said channels, a plurality of springs each mounted on one` ofsaid heads and tending to withdrawl an end of therespective pin intosaid head, a coupling; connected to said driven shaft for rotationtherewith and being coaxially positioned with said driving` shaft, saidcoupling member having a plurality of surfaces formed therewith forreceiving said pins and connecting said heads with said coupling forrotation together and means for moving said pins against said couplingsurfaces against the action of said springs upon rotation of saiddriving shaft.
